sign of juliani cardenas. >> reporter: it's a good thing they have not found jose esteban rodriguez's car yet because it gives them hope juliani cardenas is still alive. >> reporter: investigators have recovered four cars from the canal. a red mustang pulled friday morning. none of them matched the car jose esteban rodriguez was driving when he kidnapped juliani cardenas from his grandmother's home on tuesday. authorities say their strongest lead is from a farm worker who saw a similar car driving to the canal. that's why investigators haven't given up their search. >> the fact we don't have a electronic trace, confirmed sightings, all this leads us to

believe right now is the most credible lead. >> reporter: on saturday morning investigators say they are going back to where they pulled the first car on wednesday. they plan to send a camera under the water. to see if the car he was driving may be in there. >> we will send the equipment back in that area, the dive team was unable to get that equipment through the tunnel because our window was used up trying to secure a cable. the plan is to send that sonar into the tunnels after they shut the water flow down, which gives us 30 minutes to search all the way down, 50 to 100 feet down and see if there is any items or objects in the tubes. >> reporter: for the first time

juliani cardenas family closed the garage door for privacy. investigators will be back at the canal at 8:00 a.m. tomorrow. as for the amber alert signs they are still trying to decide whether to keep them on or turn them off. as for tire tracks found, they are being analyzed by the fbi and the results haven't been released yet. reggie kumar, kron 4 news. >> yuriy kokhanyy mother does not believe her son and his kidnapper are in the canal. she thinks he is hiding out. as kron 4's rob fladeboe reports, she is waiting for her son to come home. >> he was living with me. >> reporter: riding a roller coaster of emotion she showed photos of her son in happier times before jose esteban rodriguez began hearing voices. >> he told me that they were

telling him to stay away from me and do bad things. but he just wasn't listening to them. i said you need to go see a doctor. you have schizophrenia. i thought he looked cute. >> reporter: he shows me his bedroom. and his many trophies, stuffed animals and toys. >> i had a dream last night that he came home. sometimes i picture him outside in the backyard and like me running out there and grabbing him and -- >> reporter: a candle burns in the window. her grandma serves coffee in the kitchen as they wait for news and outside for another ride. >> all you people that work at the gas stations, call if you

see him. call 911. i need my son back. >> barry: rob fladeboe, kron 4 news. >> kron 4 learned the suspect jose esteban rodriguez has an extensive criminal record. we have also discovered he is being investigated for a recent domestic violence case. as kron 4's terisa estacio reports, it's unclear why he is a free man. >> reporter: in 2008 following a trip to the aquarium he and his date stopped in at a restaurant and got into a fight. witnesses saw the argument and told police about it, he was charged with domestic violence but never showed up in court and a warrant was issued. again that was in 2008. since then he had a number of run ins with the law but allowed to be free. in 2009 he was arrested twice

for dui and resisting arrest. still not turned over to authorities. then in 2010 in august he was investigated for another domestic violence case. and still not caught and turned in for the warrant. we have called the attorney's office multiple times asking them why. when he was in custody for the outstanding warrant. but officials haven't returned our calls. off the record i have been told it is unclear why this happened and they are looking in to it. the district attorney has since retired. terisa estacio, kron 4 news. >> stay with kron 4 for continuing coverage the search for juliani cardenas and go to www.kron.com anytime for updates. we are still seeing clear skies and temperatures are falling off in some places.

new details tonight, investigators are getting some solid clues as to why a pg&e gas pipeline explode intone last september. it killed eight people and destroyed 38 homes. tonight they released a report saying they found dozens of defects. kron 4's da lin has more on that report. >> reporter: based on this report released friday, experts say they have a good idea why this pipeline burst. in the report a group of engineers examined this pipe taken from san san bruno's blast site and found defect in wells that held the pipe together. it's a picture taken from the report. this is a cruces cut view of

the people. the bottom part wasn't welded. the welding is supposed to penetrate through the entire thickness of the middle. not half the thickness. the experts say because the wilding didn't penetrate through the medal it led to gaps like this one and cracks like this and they made the pipe very weak. experts say this kind of poor quality welding wasn't up to code back then and now. it was found in many parts of this pipe. what made malters worse, pg&e admits to having increased pressure in the pipe a number of times as demand grew. they are not saying the defect said in the welds caused the explosion. this report is a way to tell the public some of the laws and facts they found. it will release the result oz on a later date.

do other pipelines underneath the bay area have the same defects? >> we don't know because the record keeping by pg&e is so inferior, poor, they have admitted there is 400 miles of their system where they do not know what they have under the ground. if you don't know, you can't properly inspect. >> reporter: the president released a statement on their website saying he implemented all the recommendations to increase safety. >> all pipelines that are of a similar size to the line in san bruno are continuing to operate at pressures that have been reduced by 20%. >> reporter: law d, kron 4 news. hu jintao raps up his visit
